Therefore, the current management efficiency of interfacing different SD-OTNs is poor.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

In the description of the present application, "/" means "or" unless otherwise indicated, for example, a/B may mean a or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Further, "at least one", "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.

In the SD-OTN technology, the SD-OTN mainly used in the early stage of the communications carrier is equipment provided by a fixed manufacturer (such as a device manufacturer), and the SD-OTN of a single manufacturer is used to complete networking, and when in docking, the docking of ports can be directly realized by connecting fibers in the network management of the manufacturer, and the management of the ports to be docked can be realized by the network management system of the manufacturer. With the development of SD-OTN technology, manufacturers of SD-OTN are increasing, and in the subsequent process of SD-OTN subsidence networking coverage, communication operators gradually introduce SD-OTN devices of multiple manufacturers (different manufacturers) to perform subsidence networking coverage. Because the network management systems used by different manufacturers are different, the port can not be directly connected through the connecting fiber like the SD-OTN of a single manufacturer, so that the remote physical topology corresponding to the SD-OTN line cards of two manufacturers is inconvenient to manage, the SD-OTN connection management of different manufacturers is affected, and particularly, the management efficiency of the configuration of the line side plate cards of two manufacturers is affected.

Currently, the configuration check is needed to be performed on the docking management (such as configuration monitoring, resource early warning, etc.) of different SD-OTN (such as different manufacturers and different types of SD-OTN) devices by manually based on an independent network management (network management) system provided by each SD-OTN provider, and different network management interfaces are needed to be clicked in the implementation of each step. Moreover, when the network docking information is presented in the form of an Excel table or the like, the information is displayed due to the lack of a visual graphical interface, so that the information display effect is poor. And network configuration information can be obtained only by manually inquiring a network manager, and real-time monitoring and resource analysis processing of the network configuration information of the docking port cannot be realized.

The SD-OTN docking management method provided by the embodiment of the application can be applied to an SD-OTN docking management system. Fig. 1 shows a schematic structural diagram of the SD-OTN docking management system. As shown in fig. 1, the SD-OTN docking management system 10 includes: an electronic device 11, a coordinator 12, and a server 13.

The SD-OTN docking management system 10 may be used for the internet of things, and the SD-OTN docking management system 10 (such as the electronic device 11, the coordinator 12, and the server 13) may include a plurality of central processing units (central processing unit, CPU), a plurality of memories, a storage device storing a plurality of operating systems, and other hardware.

The electronic device 11 may be used for the internet of things and is used for realizing data processing, for example, the electronic device 11 may interact with the coordinator 12 to obtain network element data of the SD-OTN, so as to determine whether the SD-OTN docking ports are matched, so as to realize management of the SD-OTN docking.

The coordinator 12 is configured to obtain data, as shown in fig. 1, and the coordinator 12 interacts with a plurality of servers 13 to obtain network element data of a plurality of SD-OTNs, and transmits the network element data to the electronic device 11.

The server 13 is configured to store data, for example, the server 13 may be a network management server of each SD-OTN provider (for example, each SD-OTN manufacturer), and the network management server of each manufacturer stores network element data of the SD-OTN of the manufacturer.

Optionally, network element data of SD-OTN of all models of each manufacturer is stored in a network management server of each manufacturer.

An SD-OTN docking management method provided in an embodiment of the present application is described below with reference to the accompanying drawings.

As shown in fig. 2, the SD-OTN docking management method provided in the embodiment of the present application includes S201 to S204:

s201, determining a butt joint port between the first SD-OTN and the second SD-OTN.

Wherein, the butt joint port includes: a first port on the first SD-OTN and a second port on the second SD-OTN.

Optionally, notes may be made for two ports that need to be docked according to a preset naming standard, so that the port names of the ports are manually determined, so that the electronic device can determine the first port and the second port that need to be docked according to the port names of the ports.

For example, the naming standard may be link# "a vendor ID number" - "slot number"/"port number" & "B vendor ID number" - "slot number"/"port number".

For example, according to the naming standard, the port name of a first port on a first SD-OTN may be A1-001/200& B1-003/400, and the port name of a second port on a corresponding second SD-OTN may also be A1-001/200& B1-003/400, i.e., the port names of the two ports may be the same for the two SD-OTN ports that need to be docked.

It should be noted that, for the same SD-OTN, there may be multiple ports, multiple SD-OTNs are docked, and for different ports, the corresponding port names are different, so that the electronic device may determine, according to the port name of each port, the port information of the SD-OTN that the port is docked with.

Optionally, when there is a docking relationship between multiple ports, the electronic device may determine multiple docking groups according to the port name information of each port by comparing port name information in the network element data, and establish a port docking topology relationship. Wherein each docking group includes a pair of docking ports.

Optionally, the port docking topology relationship may be established differently due to different docking manners of the ports.

For example, for the port of the OTN three-hybrid circuit board, the topology relationship of the port docking can be directly established by comparing the port names. For the ports which are butted by the synchronous digital hierarchy (synchronous digital hierarchy, SDH) optical board butt joint, the virtual interface butt joint of the OTN three-mixed circuit board and the like, the port butt joint mode may be provided with a linear multiplexing section or an annular multiplexing section for protecting the butt joint, so that when the port butt joint topological relation is established by the electronic equipment, the ports which are butted by the SDH optical board butt joint and the virtual interface butt joint of the OTN three-mixed circuit board also need to acquire the configuration information of the linear multiplexing section and the configuration information of the annular multiplexing section by a coordinator, and further, the two pairs of butt joint ports under the configuration information of the linear multiplexing section and the configuration information of the annular multiplexing section are respectively set into a main protection group and a standby protection group by the comparison of port names, thereby the establishment of the port butt joint topological relation is completed.

By the method, the comparison of the information such as the port names and the like can be realized based on the electronic equipment, and the comparison is not needed through a network manager, so that the management efficiency is improved.

Optionally, for newly established SD-OTN docking, unified naming and marking (modifying port names) can be performed in the network management server, and the electronic device is used to collect the corresponding topological relation, so as to further realize checking and configuring the configuration information of the newly established docking port.

Optionally, the topology relation of all the docking ports can be associated in the electronic device, and an SD-OTN management system can be established to manage docking of the SD-OTN through the SD-OTN management system.

S202, acquiring network element data of the first SD-OTN and network element data of the second SD-OTN.

Wherein the network element data comprises: physical information including a device model and a board model, and configuration information indicating parameter configuration of each port on the SD-OTN.

Alternatively, the network element data of the SD-OTN may be understood as the network element data of each port in the SD-OTN.

Optionally, the specific type of network element data may be adjusted in connection with specific traffic requirements (e.g. direction of resource analysis).

Optionally, the physical information may further include information such as a name of a network element device (i.e. a device to which the docking port belongs), rack information (e.g. a rack identifier), frame information (e.g. a frame identifier), slot positions, board card information (e.g. a board card identifier, a board card parameter, etc.), a board card name, port information (e.g. a port identifier), a port name, etc.

It should be noted that the physical information is mainly used for positioning the SD-OTN port, for example, to indicate a data object when acquiring data, to indicate a modification object when modifying the parameter configuration, and the like.

Optionally, the network element data may further include an online state of the network element device, so as to ensure that the network element device is in the online state when the network element data is acquired and the configuration information of the port is adjusted subsequently.

Optionally, the network element data may further include information such as optical power of the port, slot occupied state, board occupied state, and port occupied state, so as to provide a reference in the management of docking the SD-OTN, for example, when the configuration information of the port needs to be adjusted, the port occupied state is combined to adjust.

S203, determining a target model according to the physical information of the first SD-OTN and the physical information of the second SD-OTN.

The target model is a predetermined butt joint model of the first port and the second port.

Optionally, the electronic device may determine a docking mode of the first SD-OTN and the second SD-OTN according to the device model of the first SD-OTN, the board card model of the first SD-OTN, the device model of the second SD-OTN, and the board card model of the second SD-OTN, and further determine a docking mode of the first port and the second port according to the docking mode of the first SD-OTN and the second SD-OTN, and determine a corresponding target model between the first port and the second port.

It should be noted that, the docking mode of the first port and the second port depends on the docking mode of the first SD-OTN and the second SD-OTN, that is, when the docking mode of the first SD-OTN and the second SD-OTN is the docking of the OTN three-hybrid circuit board, the docking modes of the ports of the first SD-OTN and the second SD-OTN quality inspection are all the docking of the OTN three-hybrid circuit board.

Alternatively, a docking model between a plurality of ports may be preset in the electronic device based on parameter configuration experience of different docking ports.

For example, as shown in fig. 3, based on the current main port docking mode, preset docking models such as an OTN three-hybrid circuit board docking model, an SDH optical board docking model, and an OTN three-hybrid circuit board SDH virtual interface docking model may be set in the electronic device.

S204, based on the target model, the configuration information of the first port and the configuration information of the second port, and under the condition that the first port and the second port are not matched, the configuration information of the first port and the configuration information of the second port are adjusted.

Optionally, the preset multiple docking models may be models of standard configuration information of different docking ports, so as to determine whether docking between two ports is matched based on whether the configuration information of the ports is consistent with the standard configuration information of the ports specified by the docking model.

Optionally, after the configuration information of each port is determined by the electronic device, an SD-OTN (e.g., a different manufacturer SD-OTN) docking configuration information file (e.g., a different manufacturer SD-OTN docking configuration information inspection table, an inspection legend, etc.) may be further generated by the electronic device, so as to display the configuration information of each port, and indicate whether the configuration information of the port meets the requirement.

Optionally, for the configuration information of a certain port which does not meet the requirement, the electronic device can perform marking processing such as marking red and thickening on the configuration information, so that the real-time monitoring and displaying of the configuration information of the port can be performed more intuitively.

Optionally, when the configuration information of a certain port is determined to be not in accordance with the requirement (i.e. not matched), the configuration information of the port can be modified through the electronic device, and the modified configuration information is issued to the SD-OTN network management server corresponding to the port through the coordinator.

Optionally, the configuration information to be modified can be uniformly modified in batches through the electronic equipment, and the modified information is issued to the corresponding network management server through the coordinator.

Optionally, when the modification information is issued, the positioning of the port in the network management server may be implemented according to the equipment model of the port, the rack information (such as a rack identifier), the frame information (such as a frame identifier), the slot position, the board card information (such as a board card identifier, a board card parameter, etc.), the board card name, the port information (such as a port identifier), the port name, etc.

In the embodiment of the present application, when performing docking management on the SD-OTN, a first port on the first SD-OTN and a second port on the second SD-OTN are determined, and network element data of the first SD-OTN and network element data of the second SD-OTN are obtained, so that a predetermined target model corresponding between the first port and the second port is determined according to physical information in the network element data of the first SD-OTN and physical information in the network element data of the second SD-OTN. And further adjusting the configuration information of the first port and the configuration information of the second port based on the target model, the configuration information of the first port and the configuration information of the second port when the first port and the second port are not matched. By the method, the configuration information of the first port and the configuration information of the second port can be automatically checked based on the network element data of the first SD-OTN, the network element data of the second SD-OTN and a preset target model, and the configuration information of the first port and the configuration information of the second port are adjusted under the condition that the first port and the second port are not matched, so that the automatic management of the docking ports of different SD-OTNs is realized, and the management efficiency of docking of different SD-OTNs is improved.

In a possible implementation manner, as shown in fig. 4, in an SD-OTN docking management method provided in the embodiment of the present application, S301 to S302 are further included:

s301, acquiring network element data corresponding to each type of SD-OTN in the SD-OTNs of the multiple types.

Optionally, the multiple types can be the equipment types of multiple SD-OTNs, the board card types and other type information.

Optionally, the network element data of the SD-OTN device may be obtained from a network management server of the SD-OTN through a coordinator.

S302, determining a plurality of docking models based on network element data corresponding to each model of SD-OTN in the SD-OTNs of the plurality of models.

Each of the plurality of docking models is used for indicating configuration information of docking ports between SD-OTNs of any two models.

Alternatively, the configuration information of the universal port of the SD-OTN board card ports with different models can be determined according to the docking configuration experience of the SD-OTN board card ports with different models, so as to determine docking models of the SD-OTN with different models.

Alternatively, a plurality of docking models defining relevant parameter configurations of the docking ports may be preset based on parameter configuration experiences of different docking ports.

For example, a docking configuration model (i.e., a docking model) may be established based on docking generic configurations of different model board card ports.

Optionally, a plurality of docking models can be established according to the equipment model, the board card model, the configuration information of the ports, the configuration information of the protection group and the like of the board card ports of different manufacturers.

Optionally, the network element data of the SD-OTN may further include network element configuration information of the SD-OTN (i.e., network element configuration information of each port in the SD-OTN), so as to obtain a protection group configuration of each port according to the network element configuration information of each port.

In the embodiment of the application, based on the early port configuration experience, a plurality of docking models are preset to realize automatic checking of the relevant configuration parameters of the docking ports based on the docking models, so that the accuracy of docking management of the SD-OTN is improved.

In one possible implementation, the object model includes: the target configuration information includes standard configuration information of the first port and standard configuration information of the second port, as shown in fig. 5, in the SD-OTN docking management method provided in the embodiment of the present application, S401-S403 are further included:

s401, determining whether the configuration information of the first port is the same as the standard configuration information of the first port according to the target configuration information corresponding to the target model.

S402, determining whether the configuration information of the second port is the same as the standard configuration information of the second port according to the target configuration information corresponding to the target model.

S403, when the configuration information of the first port is inconsistent with the standard configuration information of the first port, and/or the configuration information of the second port is inconsistent with the standard configuration information of the second port, determining that the first port and the second port are not matched.

For example, the target model may include (indicated with) standard configuration information a and standard configuration information B, where the standard configuration information a is used to indicate standard configuration information of the first port (i.e., configuration information of the first port meeting the service requirement), and the standard configuration information B is used to indicate standard configuration information of the second port (i.e., configuration information of the second port meeting the service requirement).

Alternatively, the standard configuration information may be understood as parameter configuration information of the port in a normal state (or specified by a related protocol).

It should be noted that, if a parameter exists in the first port but does not exist in the second port, the parameter in the standard configuration information of the first port in the target model is configured to be null, that is, the parameter needs to be turned off.

Optionally, each parameter included in the configuration information of the first port may be compared with each parameter included in the standard configuration information of the first port, so as to determine whether the configuration information of the first port is consistent with the standard configuration information of the first port included in the target configuration information; and comparing each parameter included in the configuration information of the second port with each parameter included in the standard configuration information of the second port, so as to determine whether the configuration information of the second port is consistent with the standard configuration information of the second port included in the target configuration information.

When any parameter in the configuration information of the first port is different from the parameter included in the standard configuration information of the first port, the configuration information of the first port is considered to be inconsistent with the standard configuration information of the first port included in the target configuration information.

For example, for the parameter item a in the configuration information of the first port, the value of the parameter a is 100, and in the standard configuration information of the first port included in the target configuration information, the value of the parameter a is 1, where the configuration information of the first port is considered inconsistent with the standard configuration information of the first port included in the target configuration information.

Optionally, when the configuration information of the first port is inconsistent with the standard configuration information of the first port included in the target configuration information, or the configuration information of the second port is inconsistent with the standard configuration information of the second port included in the target configuration information, the relevant parameter configuration (configuration information) indicating that the first port is docked with the second port is different from the standard parameter configuration (configuration information), and it is determined that the docking of the first port with the second port does not meet the predetermined requirement (the first port is not matched with the second port).

It should be noted that, because the docking ports indicated by different docking models are different, there is a difference between the standard configuration information of the first port and the standard configuration information of the second port of the target model; in addition, for the standard configuration information of the first port and the standard configuration information of the second port of the same target model, the standard configuration information of the first port and the standard configuration information of the second port are different due to different types and manufacturers of the ports.

In the embodiment of the application, the target configuration information of the target model is compared with the configuration information of the docking port, so that a plurality of parameters defined based on the target model are realized, whether the first port is matched with the second port is determined, the configuration information of the first port and the configuration information of the second port are automatically checked, and docking management of the SD-OTN is realized.

In one design, as shown in fig. 6, in an SD-OTN docking management method provided in the embodiment of the present application, S501-S503 are further included:

s501, acquiring network state information of a first port and network state information of a second port.

Wherein the network status information includes at least one of: wavelength-division multiplexing (WDM) cross-connect time slots, the number of SDH virtual ports of the synchronous digital hierarchy, SDH cross-connect time slots.

Optionally, the network state information of the port may be obtained from a network management server corresponding to the port through the coordinator.

It should be noted that, for each port network status information, specific port docking modes and resource monitoring requirements may be combined to adjust.

For example, for the port of the OTN three-hybrid circuit board, network state information such as WDM cross connection time slots of the port, the number of SDH virtual ports, and the like can be obtained; for SDH butt joint ports and SDH butt joint virtual ports, network state information such as SDH cross connection time slots of the ports can be obtained.

S502, according to the network state information of the first port, determining a first resource occupancy rate of the first port, and according to the network state information of the second port, determining a second resource occupancy rate of the second port.

Alternatively, the resource occupancy may be determined based on the ratio of the actual resources used by the port to the total capacity of the port.

It should be noted that, for different docking modes, the modes of determining the resource occupancy rate will also be different due to different types of resources used.

For example, for a docking port for docking an OTN tri-hybrid circuit board, the docking port may be classified into otu4=100G, OTU 2= G, OTU 1=2. G, OTU 0=1.25G and the like according to a rate of a class of an optical conversion unit (optical transform unit, OTU) of an interface type. Further, define the number m of interface total capacity equivalent optical data units (optical data unit, ODU) ODU0, OTU4: m=80, otu2: m=8, otu1: m=2, otu0: m=1.

Further, the WDM cross-connect time slot of the port and the number of SDH virtual ports are obtained from the network management server. According to the OTN principle: odu4=10odu2=40odu1=80odu0, oduflexkn=nodu0, so when calculating the WDM time slot occupation situation, the WDM cross-connect time slot may be converted into an equivalent ODU0, and the number of actually occupied ODUs 4, ODU2, ODU1, ODU0 is set to n4, n2, n1, n0. The SDH virtual interface number is equivalent to ODU2 or ODU1 according to the set STM-N, and the actual occupied number is set as N2x and N1x. ODUflexKn occupies the number of ODU0 as nk1, nk2, nk3 … … nkn.

To sum up, the occupation situation of the actual equivalent ODU0 of the docking port, that is, the actual equivalent ODU 0ntotal=n4×80+ (n2+n2x) ×8+ (n1+n1x) ×2+n0+nk1+nk2+nk3+ … … nk2; then for OTN tri-hybrid board docking ports, resource occupancy = actual equivalent ODU0n total/m x 100%.

For SDH interfacing ports and SDH interfacing virtual ports, interfacing ports can be classified into STM-64=10g, STM-16=2.5g, STM-4=622M, STM-1=155M, and the like according to the synchronous transport module rank (synchronous transport module level N, STM-N) of the interface type. Defining the number of interface total capacity equivalent virtual containers (virtual container, VC) 12 as y, STM-64: y=4032, stm-16: y=1008, stm-4: y=252, stm-1: y=63.

Further, the SDH handover time slot under the port is obtained from the network management server. According to the SDH principle, vc4=63×vc12 and vc3=21×vc12, therefore, when calculating the SDH slot occupation situation, the SDH cross-connection slot can be converted into an equivalent VC12, and the number of actually occupied VCs 4, VC3, and VC12 can be set as x4, x3, and x12.

To sum up, the occupation situation of the actual equivalent VC12 of the port is available, i.e. the actual equivalent VC 12xtotal=x4×63+x3×21+x12; then for SDH port interfacing and SDH virtual ports the resource occupancy = actual equivalent VC12x total/y x 100%.

S503, when the first resource occupancy rate is greater than a preset threshold value and/or the second resource occupancy rate is greater than the preset threshold value, early warning information is sent.

It should be noted that, for the first port and the second port of the pair of the connection ports, the first resource occupancy of the first port and the second resource occupancy of the second port may not be equal due to the existence of redundant traffic (discrete traffic).

For example, for a first port of a pair of ports, there may be redundant traffic a, i.e. the traffic only has a corresponding time slot in the first port, and the second port does not involve the traffic, and in the case that other traffic is the same, the first resource occupancy of the first port is higher than the resource occupancy of the second port due to the existence of the redundant traffic a in the first port.

Optionally, for the preset threshold value for sending the early warning information, the service requirement, service experience and the like can be combined for modification.

By way of example, the preset threshold may be 80%, 75%, etc.

Optionally, the preset threshold of the first port and the preset threshold of the second port may be the same threshold or different thresholds.

In the embodiment of the application, according to different port docking modes, different calculation modes are set to calculate the actual resource occupancy rate of the port, and when the actual resource occupancy rate of the port is greater than a preset threshold, resource occupancy early warning is carried out to realize the check management of docking of the SD-OTN from the aspect of resource occupancy.

In one design, as shown in fig. 7, in an SD-OTN docking management method provided in the embodiment of the present application, S601-S602 are further included:

s601, acquiring a plurality of time slot information of a first port and a plurality of time slot information of a second port.

The time slot information is used for indicating a transmission channel corresponding to each service in the plurality of services transmitted by the port.

It should be noted that, for the services corresponding to (open) the docking ports of different SD-OTNs (such as SD-OTNs of different manufacturers), the services generally are the services from the customer premise equipment (customer premises equipment, CPE) end to the Central Office (CO), i.e., CPE-CO services, or CO-CO services, which do not have the end-to-end management capability.

Alternatively, the time slot information of each port can be obtained from the SD-OTN network management server corresponding to the port through the coordinator.

Optionally, the ports are in different docking modes, and the time slot information corresponding to the ports is also different.

For example, for an OTN tri-hybrid circuit board docking port, the slot information may be WDM cross-connect slots; for the SDH interfacing port or the SDH interfacing virtual port, the slot information may be an SDH cross-connect slot.

Alternatively, the slot information of each port is composed of a plurality of slots, each slot being used for transmitting one service.

S602, when any time slot information in the plurality of time slot information of the third port is not matched with each time slot information in the plurality of time slot information of the fourth port, determining that the service corresponding to any time slot information is discrete service.

The third port is a first port, and the fourth port is a second port; or the third port is the second port, and the fourth port is the first port.

Optionally, after obtaining the plurality of time slot information of the first port and the plurality of time slot information of the second port, the electronic device may compare whether the time slot information of two ports under any time slot corresponds to any time slot of the plurality of time slot information of the first port and the plurality of time slot information of the second port, so as to determine whether the service of any time slot is discrete service.

It should be noted that, the time slot information of two ports corresponds to each other one by one, which can be understood that the time slot exists in both ports, or the time slot has an association relationship with both ports.

For example, there is a time slot ODU2:3 under the first port, and by comparison, it is determined that there is no time slot ODU2:3 under the second port, so that it may be determined that the service corresponding to the time slot ODU2:3 under the first port is a discrete service.

Optionally, for the service determined to be the discrete service, service cleaning may be performed to save network resources, thereby improving the resource utilization of the port.

In the embodiment of the application, whether the two ports butted under each time slot are corresponding to the service or not is checked, so that the discrete service in the two butted ports is identified, the discrete service is cleaned, the resource utilization rate of the butted ports is improved, and the management efficiency of butting the SD-OTN is improved.
